完整.Net中的实体框架核心？

Question

有什么方法可以在完整的.Net Framework控制台应用程序中实现实体框架核心？

Answer 1

First you need to create console application with full .net framework, Second install these packages using package manager console,

Install-Package Microsoft.EntityFrameworkCore.SqlServer
Install-Package Microsoft.EntityFrameworkCore.Tools –Pre

Now you need to create your model and context

namespace ConsoleEfCore
{
    class Program
    {
        static void Main(string[] args)
        {
            MyContext db = new MyContext();
            db.Users.Add(new User { Name = "Ali" });
            db.SaveChanges();
        }
    }
    public class MyContext : DbContext
    {
        public DbSet<User> Users { get; set; }
        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
            optionsBuilder.UseSqlServer(@"Server=.;Database=TestDb;Trusted_Connection=True;");
        }
    }
    public class User
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }
}

then just need to use this command

Add-Migration initial

and then you need to update your database to create that

Update-Database

run project and you we'll see User would insert to your database
